CELL DIVISION “REINFORCEMENT” Name ________________________________________ DIRECTIONS 1-4: Injured and old, worn-out cells in your body are constantly being replaced by new cells. New cells are produced by the processes of mitosis and cell division. Study the four stages of mitosis shown in the pictures. Number the stages in the order in which they occur. Match the names of the stages below with their descriptions. Then answer the questions. DIRECTIONS 5-8: Label the name of each stage above. Use the word bank bold faced and italicized below to help you. DIRECTIONS 9-13: Use the word bank bold faced and italicized below to put the best letter in each blank A. prophase B. metaphase C. anaphase D. telophase ______9. The doubled chromosomes separate. Single chromosomes move to opposite ends of the spindle. ______10. Doubled chromosomes form, the nuclear envelope disappears, and the spindle forms. ______11. The cell divides in two. ______12. The spindle disappears. A nuclear envelope forms around each set of chromosomes. ______13. Doubled chromosomes line up in the middle of the spindle.
